Description
A találmány tárgya havi vérzésnél alkalmazható tampon, amely tampon lényegében hengeres, szálasanyagból kialakított abszorbens elemet, valamint egy visszahúzószálat tartalmaz, amely a tamponhoz van csatlakoztatva, és amely a tampon egyik végén van kivezetve, a szál el van látva egy szálvéggel, a tampon tartalmaz még folyadékáteresztő burkolatot, amely célszerűen hőre lágyuló anyagból van, és amely az abszorbens elemet körülfogja, a hőre lágyuló burkolat a szálvégnél a tampon középső részénél van megfelelően hőmérséklettel lezárva és tömítve, maga az abszorbens elem pedig a hossztengelyére merőleges zárófelülettel van ellátva, amely a szál végnél helyezkedik el.BACKGROUND OF THE INVENTION The present invention relates to a monthly bleeding tampon comprising a substantially cylindrical absorbent member made of fibrous material and a retraction thread which is connected to the tampon and terminated at one end of the tampon, the fiber having a fiber end. a fluid-permeable casing, preferably made of a thermoplastic material, enclosing the absorbent member, the thermoplastic casing being sufficiently sealed and sealed at the middle of the tampon at the fiber end, and the end being perpendicular to its longitudinal axis, located.
A találmány tárgya továbbá eljárás célszerűen havi vérzésnél alkalmazható tampon előállítására, ahol a tampon célszerűen hengeres, szálasanyagból kialakított abszorbens elemet, és a tamponhoz csatlakoztatott, és annak végéből kilépő visszahúzószálat, valamint folyadékáteresztő burkolatot tartalmaz, ez utóbbi hőre lágyuló műanyag és körbefogja az abszorbens elemet, a burkolatot hővel a tampon szál felőli végénél megolvasztjuk és tömítjük annak a középső részén, és az abszorbens elemet a burkolatba nyomással rögzítjük.The invention further relates to a process for the manufacture of a tampon, preferably for monthly bleeding, wherein the tampon preferably comprises a cylindrical fibrous absorbent member and a retractable fiber attached to and exiting the tampon and a fluid permeable wrapper, heat-sealing the wrap at the fiber end of the tampon and sealing it in the center portion and securing the absorbent member to the wrap by pressing.
A fent ismertetett tamponhoz hasonló megoldás van például az US-A-4.743.237 lajstromszámú szabadalmi leírásban ismertetve, amely szabadalom elsődlegesen a visszahúzószál biztonságos rögzítésére mutat be példát arra, ahogyan azt a tamponhoz lehet rögzíteni. Itt látható még egy, az abszorbens elemet vagy a tampont körbefogó burkolat is, amely adott esetben más töltőanyaggal is megtölthető, alkalmas például a filteres teáknál csomagolóelemként. A gyártás során a külső burkolat megfelelően hosszúra van kiképezve, összehasonlítva az abszorbens elem hosszúságával vagy az egyéb töltet hosszúságával. A burkolatnak az abszorbens elemen vagy egyéb töltetlen túlnyúló vége el van vékonyítva, és hőolvasztással van a szálhoz csatlakoztatva. Ez gyakorlatilag azt jelenti, hogy a szál nincs magához az abszorbens elemhez rögzítve és csatlakoztatva. A burkolat végein a hő hatására bekövetkező tömítés semmiféle kontaktusban nincs az abszorbens elemmel sem az abszorbens elem fölött, sem pedig alatta.A solution similar to the tampon described above is described, for example, in US-A-4,743,237, which primarily discloses an example of a secure fastening of a drawstring as it can be attached to a tampon. There is also a wrapper enclosing the absorbent member or tampon, which may optionally be filled with other filler material, for example as a wrapping element in filtered teas. During manufacture, the outer casing is of sufficient length relative to the length of the absorbent member or the length of the other filler. The overhanging end of the sheath over the absorbent member or other unladen member is thinned and is heat-bonded to the fiber. This practically means that the fiber is not attached to and attached to the absorbent element itself. At the ends of the casing, the heat seal is in no contact with the absorbent member, either above or below the absorbent member.
Egy további hasonló tampon van ismertetve a GB 2.011.680 lajstromszámú szabadalmi leírásban. Ezen ismert tampon abszorbens eleme az abszorbens anyagokból képezett szövedék többmenetű feltekercselésével van előállítva, és ennek a feltekercselt anyagnak van egy központi csatornája, amely az abszorbens elem tengelyében halad. Maga a tampon lágy, nemszövött anyagból készült burkolattal van ellátva, amely megakadályozza azt, hogy a tampon abszorbens anyagából a pehely kijusson, illetve kijutva a tampon a viselőjének a hüvelyében maradjon, amikor a tampont használat után kiveszik. A burkolat anyaga vissza van hajtva, és az átmenőcsatomát a tampon középvonalában legalább részben lefedi. A visszahúzószál szabadon nyúlik ki a tamponból a csatornán keresztül, és mivel a központi csatornát előzetesen kiképezték, nincs szükség arra, hogy a burkolatban erre a célra külön nyílást alakítsa20 nak ki.Another similar tampon is disclosed in GB 2,011,680. The absorbent member of this known tampon is produced by multiple winding of a web of absorbent materials and has a central channel extending along the axis of the absorbent member. The tampon itself is provided with a soft non-woven casing that prevents the fluff from escaping from the absorbent material of the tampon or remaining in the vagina when the tampon is removed after use. The casing material is folded back and at least partially covers its through channel at the center of the tampon. The retraction thread extends freely from the tampon through the duct, and since the central duct is pre-configured, it is not necessary to provide a separate opening 20 for this purpose in the housing.
A találmánnyal célul tűztük ki az előbb említett tampon oly módon történő továbbfejlesztését, hogy segítségével az előzőeknél hatásosabb módon lehessen megakadályozni, hogy a tamponból a testfolyadék ki25 szivárogjon.It is an object of the present invention to further develop the aforesaid tampon in such a way that it prevents leakage of body fluid from the tampon in a more effective manner.
Cél volt továbbá, hogy a találmány szerinti tampon nagyobb stabilitással rendelkezzen, mint az ismert megoldások. Kívánatos volt az is, hogy megakadályozzuk azt, hogy a tampon végénél lévő húzószál kiszélesedjen vagy megduzzadjon akkor, ha a tampon a testfolyadékot elnyeli, azaz a már használt tampon is olyan alakú legyen, hogy könnyen lehessen eltávolítani.It was a further object that the tampon of the present invention should have greater stability than the prior art. It was also desirable to prevent the tongue at the end of the tampon from widening or swelling when the tampon absorbs body fluid, i.e., the tampon already in use is shaped so that it can be easily removed.
További cél volt, hogy a tamponnál biztosítva legyen, hogy a külső burkolat az abszorbens elemhez nagyobb biztonsággal legyen rögzítve, mint az ismert megoldásoknál. Természetesen az ily módon kialakított tamponnak is megfelelő komfortérzetet kell biztosítania.A further object was to ensure that the tampon was provided with a more secure attachment of the outer casing to the absorbent member than is known in the art. Of course, a tampon designed in this way should also provide a comfortable feeling.
A találmány tehát havi vérzéshez alkalmazható tam40 pon, amely egy lényegében hengeres, szálasanyagból készült abszorbens elemet, a tampon kihúzására alkalmas szálat tartalmaz, amely a tamponhoz van csatlakoztatva, és amely a tamponnak egyik végén van kivezetve, a szál megfelelő véggel van ellátva, és a tampon egy folyadékáteresztő burkolattal van borítva, amely célszerűen hőre lágyuló anyag, és amely az abszorbens elemet körülveszi, és a tamponnak a középső részén a szál a tampon végén hővel van összeolvasztva, maga az abszorbens elem pedig egy, a szálkivezetésnél az abszor50 bens elem hossztengelyére merőleges felülettel van kiképezve.Thus, the invention is applicable to a monthly bleeding tamper puncture comprising an essentially cylindrical absorbent member made of fibrous material, a tampon pulling fiber attached to the tampon, which is terminated at one end of the tampon, and has a corresponding end. the tampon is covered with a fluid-permeable wrapper, preferably a thermoplastic material, which surrounds the absorbent member, and in the central portion of the tampon, the fiber is heat-fused at the end of the tampon, and the absorbent member is a perpendicular to the fiber outlet. surface.
A találmány szerinti tampon lényege abban van, hogy a burkolat a szálhoz közelebbi végén az abszorbens elem hossztengelyére merőleges felületével szoros érintkezésben van, maga a burkolat hőmérséklet hatására összeolvadó, egy lényegében folyadékzáró, célszerűen műanyag filmet képez, és legalább a zárófelületként kiképezett vége központi részén az abszorbens elem szálai olvasztással vannak a burkolathoz csatla60 koztatva a hővel megolvasztott tartományon belül.The essence of the tampon according to the invention is that the wrapper is in close contact with the fiber at its end perpendicular to the longitudinal axis of the absorbent member, forming a substantially fluid-tight, preferably plastic film fused by the wrapper at least centrally to its end. the fibers of the absorbent member are fused to the casing within the heat-melted region.

A találmány tárgya továbbá a találmány szerinti tampon előállítása, a bevezetőben említett eljárással.The invention also relates to the preparation of a tampon according to the invention by the method mentioned in the introduction.
Az eljárás lényege abban van, hogy az összenyomást követően a burkolatot a tampon hossztengelyére merőleges végének legalább középső részén lényegében folyadékzáró réteggé hegesztjük össze, és az abszorbens elem szálait a burkolathoz olvasztással rögzítjük a burkolat hővel lezárt tartományában.The essence of the process is that, after compression, the wrapper is welded to a substantially liquid barrier layer at least in the central portion of its end perpendicular to the longitudinal axis of the tampon and the fibers of the absorbent member are fused to the wrapper in the heat sealed region of the wrapper.
Előnyös az eljárás, ha az olvasztásos hőtömítést meleg tüskével vagy egyéb fűtött elemmel végezzük el úgy, hogy a tüskét vagy egyéb fűtött elemet a burkolattal ellátott tampon szál felőli végéhez nyomjuk, hogy azzal nyomás alatt érintkezzen, és mindaddig nyomjuk, amíg a hőre lágyuló burkolat anyaga egy lényegében folyadékzáró réteggé, például műanyag filmmé olvad össze, majd ezután a tüskét a felületről eltávolítjuk.It is advantageous to perform the fusion heat seal with a hot mandrel or other heated member by pressing the mandrel or other heated member onto the fiber end of the tampon with the jacket under pressure and until the material of the thermoplastic jacket is pressed. melting into a substantially fluid-tight layer, such as a plastic film, and then removing the mandrel from the surface.
Előnyös még az eljárás akkor is, ha a tampont burkolatának anyagát a szállal szomszédos végén a palástfelületének egy részén is folyadék-átnemeresztővé tesszük a hőolvasztással.It is also advantageous if the material of the tampon casing is made liquid-impermeable by heat-melting at a portion of its peripheral surface adjacent the thread.
A megolvasztott burkolat anyaga többé-kevésbé folyadékzáró, és a tampon azon végénél, ahol a kihúzószál rögzítve van, szivárgást megakadályozó tartomány képződik. Nem szükségszerű, hogy ez a rész teljes egészében folyadékzáró legyen, a szivárgással szembeni hatásfok azonban olyan mértékben nő, ahogy ez a folyadékzáró rész a tampon végénél nő. A megolvasztott burkolat a tampon végét stabilizálja, és ily módon megakadályozza, hogy a tampon vége megduzzadjon, ha a tampon a testfolyadékot elnyeli.The material of the molten casing is more or less liquid-tight and forms an anti-leak region at the end of the tampon where the pull-out strand is fixed. It is not necessary for this portion to be completely impermeable, but the leakage efficiency will increase to the extent that this impermeable portion increases at the end of the tampon. The molten casing stabilizes the end of the tampon and thus prevents the end of the tampon from swelling when the tampon absorbs body fluid.
Maximális lágyság biztosítható a hengeralak külső felületén vagy a palástfelületen a találmány szerinti tamponnál, ha a végén lévő felület hőhatással lezárt tartománya nem terjed a palástfelületre. Jóllehet a hőhatással tömített tartomány adott esetben a teljes felület mentén kialakítható, sőt előnyös lehet egy olyan kiviteli alak is, amikor a palástfelület egy részén is kialakul ez a tömített zárótartomány anélkül, hogy a komfortérzetet csökkentené. Ez az elrendezés ugyanis nagyobb biztonságot jelent a folyadék szivárgásával szemben, azonkívül pedig nagymértékben növeli a tamponnál a szál végének a stabilitását, és ily módon teszi egyszerűbbé és könnyebbé a tampon behelyezését és eltávolítását.Maximum softness can be achieved on the outer surface of the cylindrical surface or on the peripheral surface of the tampon according to the invention if the heat sealed region of the end surface does not extend to the peripheral surface. Although the thermally sealed region may optionally be formed along the entire surface, it may even be desirable to provide a portion of the circumferential surface that provides this sealed closure without compromising comfort. This arrangement provides greater security against liquid leakage and greatly increases the stability of the fiber end of the tampon, thereby making the insertion and removal of the tampon simpler and easier.
Az a hőre lágyuló anyag, amelyet a tampon burkolataként használunk, célszerűen nemszövött anyag. Egyéb anyagok, például perforált film vagy hőre lágyuló háló is alkalmazható Minden olyan anyag alkalmazható, amely hőre lágyuló műanyag, így tehát jól alkalmazható polietilén vagy polipropilén. A műanyagok adott esetben keverékben is jelen lehetnek, vagy kétkomponensű szálakból is kialakíthatók. A tampon teljes burkolata előnyösen egyrészt azonos anyagból van kialakítva, mivel ez a gyártást nagymértékben megkönnyíti.The thermoplastic material used as the wrapper for the tampon is preferably a nonwoven material. Other materials, such as perforated film or thermoplastic mesh, may be used. Any material which is thermoplastic, so that it is well-suited to polyethylene or polypropylene. The plastics may optionally be present in a mixture or may be formed from two-component fibers. Preferably, the entire wrapper of the tampon is made of one and the same material, since this greatly facilitates the manufacture.
A találmányt a továbbiakban példakénti kiviteli alakjai segítségével, a mellékelt ábrákon mutatjuk be részletesebben.The invention will now be described in more detail by way of exemplary embodiments, in the accompanying drawings.
Az 1. ábrán egy ismert tampon vázlatos keresztmetszete látható a gyártás egyik fázisában, a 2. ábrán pedig oldalnézetben, részben tengelyirányú metszetben a találmány szerinti tampon egyik kiviteli alakja látható.Figure 1 is a schematic cross-sectional view of a known tampon at one stage of manufacture, and Figure 2 is a side view, partly in axial section, of an embodiment of the tampon of the present invention.
A 8 tampon úgy készül, hogy abszorbens anyagból készült, négyszögletes alakú 1 szövetet spirálisan több menetben feltekernek, ezek közül az 1. ábrán két menet látható. Az 1 szövetből képezett menetek hengeres 2 abszorbens elemet képeznek, amelyben központosán egy 3 csatorna van, amely tengelyirányban áthalad a 8 tamponon. Az abszorbens anyag önmagában ismert, az adott célra használható bármilyen anyag lehet, lehet például szálasanyag, amelyet abszorbens cellulózpehelyből állítottak elő, például rayon- vagy gyapjúszál. A 2 abszorbens elem kis mennyiségben termoplasztikus kötőanyagokat, például kötött szálakat vagy hasonlókat is tartalmazhat, amelyek a kész tampont stabilizálják.The tampon 8 is made by wounding the rectangular tissue 1 of absorbent material in a spiral in several turns, of which Figure 1 shows two turns. The threads of tissue 1 form a cylindrical absorbent member 2 with a centrally located channel 3 extending axially through the tampon 8. The absorbent material is known per se and can be any material suitable for the purpose, for example, a fibrous material made from an absorbent cellulose fluff, such as rayon or wool. The absorbent member 2 may also contain small amounts of thermoplastic binders, such as knitted fibers or the like, which stabilize the finished tampon.
A 2 abszorbens elem teljes palástfelületére hőre lágyuló műanyagból készült nemszövött 4 burkolat van elhelyezve. A 4 burkolat hossza a hossztengelye irányában nagyobb, mint a 2 abszorbens elem hossztengely irányába eső hossza, és a 4 burkolat két végén kiálló 5 és 6 végrészek a 3 csatornába vannak behajtva. A 2 abszorbens elemhez egy, a 8 tampon kihúzását elősegítő 7 szál van rögzítve úgy, hogy ezt a 7 szálat a menetek egyike körül elhelyezett hurokként rögzítjük. A 7 szál végei a 2 abszorbens elemből a központi 3 csatornán keresztül nyúlnak ki.A nonwoven casing 4 made of thermoplastic is disposed on the entire peripheral surface of the absorbent member 2. The length of the cover 4 in the longitudinal direction is greater than the length of the absorbent member 2 in the longitudinal direction and the end portions 5 and 6 protruding at each end of the cover 4 are folded into the channel 3. Attached to the absorbent member 2 is a thread 7 to facilitate the pulling out of the tampon 8 by attaching this thread 7 as a loop around one of the threads. The ends of the fiber 7 extend from the absorbent member 2 through the central channel 3.
Az 1. ábrán látható félkész 8 tampont ezt követően összenyomjuk vagy valamilyen módon kompaktabbá tesszük elsődlegesen sugárirányban, és így kapjuk meg a rúd alakú 8 tampont. A 2. ábrán egy ilyen rúd alakú 8 tampon látható a rúd egyik oldala felől úgy, hogy a külső része részben el van távolítva. A 2. ábrán látható még egy fűtött 9 tüske, amely a 8 tamponnak azon 10 végével szemben helyezkedik el, ahol a 7 szálat kivezetjük. A 9 tüskét a 10 vég irányába oda-vissza lehet mozgatni, ahogyan ezt a P nyíl jelzi. Ha az 1. ábrán látható félig kész 8 tampont végső alakjára nyomjuk össze, a következő lépésben a 9 tüskét a 10 végnekThe semi-finished tampon 8 shown in Fig. 1 is then compressed or somehow compacted primarily radially to obtain a bar-shaped tampon 8. Figure 2 shows such a bar-shaped tampon 8 from one side of the bar with the outer portion partially removed. Fig. 2 shows another heated mandrel 9 located opposite the end 10 of the tampon 8 where the thread 7 is led out. The mandrel 9 can be moved back and forth towards the end 10 as indicated by the arrow P. By pressing the semi-finished tampon 8 of FIG. 1 to the final shape, in the next step, the mandrel 9
HU215 812B nyomjuk. A 9 tüskét olyan hőmérsékletre fütjük, amelyet a 4 burkolat anyaga alapján választunk meg, amely hőre lágyuló anyag, hogy a hő hatására ez a hőre lágyuló anyag, amikor a 9 tüskével érintkezik, megolvadjon, és a 8 tamponnak ezen a 10 végén egy lényegében folyadék-átnemeresztő 11 műanyag filmréteget képezzen. Azt követően, hogy ezt a 11 műanyag filmréteget létrehoztuk, a 9 tüskét eltávolítjuk úgy, hogy most már a 10 véggel ne érintkezzen. A 2. ábrán látható, hogy a 9 tüske segítségével egy kagylószerű 12 mélyedést hoztunk létre a 10 végen. A 8 tamponnak a 10 végén ily módon a teljes felület mentén, amelyet a 11 műanyag film beborít, és ahol a hőre lágyuló műanyag megolvadt, egy folyadék-átnemeresztő réteg képződik, és ez a 11 műanyag film itt mindenféle szivárgást megakadályoz. Amikor a 4 burkolat anyaga megolvad, majd később megszilárdul, a 2 abszorbens elemben a szomszédos szálak is egymással összekapcsolódnak. Ily módon a 8 tampon ebben a tartományában stabilizálva és körberögzítve van. A 4 burkolat beburkolja a 2 abszorbens elemet.HU215 812B press. The mandrel 9 is heated to a temperature selected from the material of the jacket 4 which is a thermoplastic material so that the thermoplastic material melts upon contact with the mandrel 9 and a substantially liquid is formed at this end 10 of the tampon 8. to form an impermeable film of 11 plastic films. After this plastic film layer 11 is formed, the mandrel 9 is removed so that it does not come into contact with the end 10 now. Figure 2 shows that the spike 9 has been used to create a shell-like recess 12 at the end. Thus, at the end 10 of the tampon 8, a liquid-impermeable layer is formed along the entire surface covered by the plastic film 11 and where the thermoplastic has melted, and this plastic film 11 prevents any leakage there. When the material of the wrapper 4 melts and subsequently solidifies, adjacent fibers in the absorbent member 2 are joined together. In this way, the tampon 8 is stabilized and circularly fixed in this region. The cover 4 encloses the absorbent member 2.
A 2. ábrán bemutatott kiviteli alaknál a 9 tüske átmérője úgy van megválasztva, hogy kisebb legyen, mint a tampon 10 végének az átmérője. Adott esetben azonban a 8 tampon 10 végén levő teljes felület ilyen módon hővel összeolvasztható egy melegített lemez vagy hasonló segítségével, ekkor tehát nem a 9 tüskét használjuk, hanem egy megfelelő méretű melegített lemezt. Ily módon fokozottabb védelmet tudunk megvalósítani a szivárgással szemben. Egy olyan kiviteli alak is elképzelhető, amikor a 8 tamponnak a 10 végéhez közeli palástrészeit is megolvasztjuk megfelelő alakos elem segítségével, ezáltal további védelmet valósítunk meg a szivárgással szemben, mi több, a 8 tamponnak ezt a 10 végét tovább stabilizáljuk. így lehet megakadályozni, hogy a 8 tampon megduzzadjon, amikor a testfolyadékot elnyeli.In the embodiment shown in Figure 2, the diameter of the mandrel 9 is selected to be smaller than the diameter of the end of the tampon 10. However, optionally, the entire surface at the end 10 of the tampon 8 may be heat-fused by means of a heated plate or the like, so that a heated plate of a suitable size is used, not the mandrel 9. In this way, we can provide increased protection against leakage. It is also possible to melt the portions of the tampon 8 near the end of the tampon 8 by means of a suitable shaped element, thereby providing additional protection against leakage, moreover by stabilizing the tampon 8 at this end. This prevents swab 8 from swelling as it absorbs body fluid.
A példakénti kiviteli alaknál arra utaltunk, hogy a tüskét a 8 tampon 10 vége irányába, majd attól el mozgatjuk. Az eljárás megvalósítható úgy is, hogy a 9 tüske áll, és a 8 tampont mozgatjuk.In the exemplary embodiment, it was indicated that the mandrel was moved toward and away from the end of tampon 8. The method may also be implemented by standing the mandrel 9 and moving the tampon 8.
